The adventurers probably come to Brinwan not expecting a great deal, and a first encounter with a mildly insane goat herder doesn't change that expectation. However, just as the characters secure rooms and dinner for the night, something monstrous crawls from the sea and the matter of unexpected deaths in the local mine comes to light - potentially leading them down the road to adventure (although based on playtesting, you never can trust the players to do anything close to what you expected or hoped for...)
